NaHCO 3 + HCl → NaCl + H 2 O+CO 2 H 2 CO 3 → H 2 O + CO 2 (g) Sodium bicarbonate reacts with acetic acid (found in vinegar), producing sodium acetate, water, and carbon dioxide: NaHCO 3 + CH 3 COOH → CH 3 COONa + H 2 O + CO 2 (g) Sodium bicarbonate reacts with bases such as sodium hydroxide to form carbonates: NaHCO 3 + NaOH → Na 2 CO 3 ...
The only hydrates with stable melting points are NaOH·H 2 O (65.10 °C) and NaOH·3.5H 2 O (15.38 °C). The other hydrates, except the metastable ones NaOH·3H 2 O and NaOH·4H 2 O (β) can be crystallized from solutions of the proper composition, as listed above. However, solutions of NaOH can be easily supercooled by many degrees, which ...
